Abstract: An apparatus and method for sequence a "two-up" imaging drum for four color process color is provided. The sequencing provides enough separation between the receivers to operate an image fixing station as a slower throughput speed then the linear speed of the receivers exiting the transfer station and thereby provide more fusing energy and higher image quality without appreciable loss in productivity. The sequence also provides for better registration, by maintaining the receiving member conforming to the transfer drum during the total toning process.

Abstract: Magnetic brush development apparatus for applying developer material to a latent electrostatic image in which flow of developer material, distributed in balance across the length of the apparatus, is assured. The apparatus includes a housing having a portion defining a sump adapted to contain a supply of developer material. A magnetic brush is located substantially within the housing in spaced relation to the sump portion for applying developer material to the latent image. A feed mechanism, located within the housing between the sump portion and the magnetic brush transports developer material from the sump to the magnetic brush. An agitating and transporting mechanism, located in said sump portion, agitates developer material and transports developer material to the feed mechanism. In the preferred embodiment the agitating and transporting mechanism is a ribbon blender.
